Alkaline Earth Metals Alkaline Earth Metals are in group 2 and periods 2-7(shown in the table to the right). The elements in the alkaline earth metals are Beryllium, Magnesium, Calcium, Strontium, Barium and Radium. Alkaline earth metals are solids. Three properties of alkaline earth metals are that they are metallic, fairly hard and they are not malleable. Three chemical properties of alkaline earth metals are calcium, and barium can reduce hydrogen gas when heated, forming the hydride. The hot metals are also sufficiently strong reducing agents to reduce nitrogen gas and form nitrides. Magnesium can reduce, and burn in carbon dioxide. Three interesting facts about our groups are, calcium is in milk. Another is that alkaline earth metals are softer than other metals. A third is that they are not found free in nature because of their reactivity. Two common uses for our metals are calcium, which is used in milk and Beryllium occurs most commonly in gemstones, beryl, emeralds and aquamarine.
